is a specification.

, The-object of this invention is to provide en improved melme'forapplying a coating surface of metal moldscarried on e rotating table orotherwise "caused to travel in a closed circuit.

In the co-pemling a'pylicctieii of Joseph L. Dostel Serial No. 568,465,iii-co Julie 15, 1922, means are discleeel whereby such eries of moldsmay be cieenecl with compressecl air and thence ore lwiril lamplolecl:by means of e etei' 1 In the co-pencling app} 010E of the same inventor,Serial No. 598v 1922, the burner is carried or; unclulaiing track and.is causetl to roeeie wi la the rotetiiig molcis anal is automaticallyreleesecl and su bseqiientgv .re-engegel by the neri; succeedingHlOlu'bl in the present inveri tion She same principles are rcerle useof as those clisclcsieel in the aforesaid applicw 'tions but Elleconetriifition is simplifieil the cost of manufacture rei'iuceil.

Figure 1 shows a plan View of the device c apliccl to a, meliiingmachine but egly one of the pairs of molds are shown in this view.

12 is the pivot which supports this arm 5 and turns freely on 11; 13 isthe pin on which arm 5 swings in vertical plane; 14- and 15 are a pairef molds between. which the burner 1 is suspended; 31 is the rotatingtable Oll which these molds are mounted, 16 being the support to themold 14 and 17 is e plate mounted on 16 and time revolving with themelds, the purpose of which will be dcscriberllater.

In Figures 1 and 2, 18' and 19- are bearings for the horizontal shaft20. In Figure 3, 21 is a plate bolted to arm 5 and 22 is an arm lreyeclto shaft 20, 23 being a tension spring between arm 22 and plate 21.

In Figure l, 27 is an arm mounted and bolted to shaft 20 a'nrl 28 is anarm bolted to the burner 1 having a, pin 29 which is adapted to engagewith a slot in the end i the arm 27. S0 is the Pipe conveying the gas toburner Ii.

Operation-In the position in which the Figure 1 the burner l istraveling clockwise, and 15 are traveling anti-clockwise. The arm 5 willre-engege with the mold 14 by means of the project-ion 17, while theburner 1 and lliflE- arm 5 are traveling down' the inclincfil track 8eliewn in Figure 3. When engages with the arm and the molcls 14 trackWhen. 'lzlie cm 5 reaches the posiion shown ire larolren lines in Figure3 it eutomelicelly escapee over the to ,of the progecaion 17 mid igemtravels own the trecir KKK i921 'iJllQ influence of gravity.

This is eulistaiitielly invention in its simplest and thereforepreferred; form. The link 2? which pivote about the, oscillating sliefix2O merely provifiee for e slight swing lug-motion oi the burner toincrease the uniiom'iity may well be omitted, where simplicity andclieapiiees of construct-ice: is of importance.

slazioriery 8 were of iiistri'biitiou of the flame and 4 i 2 see ers thepin 24 around the fulcrum 22 which thus gives a slight rocking motion tothe burner 1. A spring 23 returns the burner to its mid position asshown in the Figure 1.

What I claim is: 1. In a molding machine, 21 moving series of moldsadapted to be opened, a, burner ad 'epted to pass between and to depositlampblack upon said open molds, a radial arm supporting said burner, aninclined track supporting said radial arm, automatic means whereby saidburner is carried forward with each oi said molds, automaticallyreleased and subsequently rc-engaged by the next succeeding mold.

2. In a molding machine, a moving series of molds adapted to he opened,a swinging burner adapted to pass between and to deposit lampblack uponsaid open molds, a

radial supporting said burner, an inclined track supporting said radialarm, automatic means whereby said burner. 15,

tionary pin engaging with said swinging burner and adapted to impartthereto an oscillating; motion.

3. In a molding machine, a moving series of molds each of which isopened for '2. pre-' determined period of time, a, burner adapted topass between said open molds, means for causing the burner to travelwith each mold through a portion of its travel and to returnautomatically sees to travel with the next succeeding mold.

In testimony whereof I aflix my signature.
